Biomass stove is a mechanism whereby the burned resources undergo a carbonization process and generate heat through the carbonization process which is used in the process of domestic needs or other design purposes tailored to the needs of the user. Thermoelectric generator technology is a solution in solving the problem of heat energy conversion on the surface of the biomass stove wall. Thermoelectric generator is a technology that does not have a big negative impact on the environment, this technology is very efficient, durable and able to get energy in small and large sizes. The purpose of this research is to produce an efficient biomass stove design with a thermoelectric generator as an energy conversion tool to produce electricity and to analyze the effect of variations in biomass fuel on thermal efficiency. The method used for this research is an experimental method. The test is carried out by verifying when the thermoelectric produces power with the consideration of cooling the cold side of the thermoelectric generator as cold as possible. The test was carried out with 5 trials and varying 3 fuels of palm shell, meranti wood and rubber wood by using a temperature difference of 70℃ boiling water as a medium for measuring time. From the test results, it is obtained that the calculation of palm shell fuel produces an average of 871 watts of fuel heat energy, meranti wood fuel produces an average of 743 watts of fuel heat energy, rubber wood fuel produces an average of 661 watts of fuel heat energy watt. The average seebeck coefficient for palm shell fuel is 0.0191 V/K, the average seebeck coefficient for meranti wood fuel is 0.0263 V/K and the seebeck coefficient for rubber wood fuel is 0.0214 V/K on average. The thermal efficiency value for the thermoelectric generator biomass stove in each experiment for palm shell fuel is an average of 4.37%, for meranti wood fuel an average of 3.01% and for rubber wood fuel an average of 4.31%. From this research, it can be concluded that using palm kernel shell fuel is the most efficient. Meanwhile, for each fuel variation, the results showed that this study was able to turn on the lamp used as lighting with specifications for LED lamps of 2 feet 3 volts of 5 watts and for sustainable energy use the energy produced by TEG was stored in DC AAA Ni-Cd batteries with a current of 600mAh. 1.2 volts.
